Two fundamental issues are incorporated in the present monograph: the issue related to the quantification of the social costs and the issue, related to the defining of the circular economy concept as a theoretical model.
The analysis is based on the methodology of the new institutional economics, which fact distinguishes it from the many other circular economy analysis based on the neo-classical methodological apparatus.
The originality of the ideas presented in the monograph is highlighted by their approbation to the United Nations Economic Commission for Europe (UNECE).

Dr. Shteryo Nozharov presented a paper on topic: „Circular economy concept implementation in the inland waterway transport“ on 4th of November 2021 (UNECE, 2021,p.13).
